Intra‐annual transfer of hydrogen and oxygen isotopic signals from water and sugar precursors to tree rings: Processes and mechanisms

open access: yesNew Phytologist, EarlyView.
Intra‐annual radial growth of beech and spruce in 2021 and 2022. Summary The oxygen (δ18O) and hydrogen (δ2H) isotope compositions of leaf and xylem water shape tree‐ring isotope baselines, while the fraction of sugars undergoing isotopic modification downstream of leaves (fO, fH) determines the dominant hydrologic signal.

Dodder seedlings benefit from apoplastic nutrition by inducing SWEET15‐mediated unloading of sucrose from the host's phloem

open access: yesNew Phytologist, EarlyView.
Cuscuta reflexa infection sites. Summary Cuscuta species are holoparasitic plants that penetrate host stems with haustoria, connect to the vasculature and exhaust water, nutrients and carbohydrates. Parasite seedlings possess only limited maternal reserves and the development of a vascular connection takes several days.

Cross‐stage single‐cell and spatial metabolome analyses reveal periderm specialization and tanshinone biosynthesis in Salvia miltiorrhiza roots

open access: yesNew Phytologist, EarlyView.
Biosynthesis and accumulation of tanshinones in the periderm of Salvia miltiorrhiza during secondary root growth. Summary Perennial herbs develop long‐lived roots that undergo repeated cycles of secondary growth, during which the periderm functions as a protective barrier and a major site of specialized metabolite accumulation.

Key sources of uncertainty in process‐based modeling of live fuel moisture content

open access: yesNew Phytologist, EarlyView.
Location of the selected live fuel moisture content (LFMC) sampling sites. Summary Process‐based models that mechanistically represent water‐carbon balances in the atmosphere‐soil–plant continuum are an attractive tool for monitoring live fuel moisture content (LFMC) dynamics, a key variable when assessing fire danger.

Conserved symbiosis‐associated genes in the cycad Encephalartos natalensis suggest co‐option for cyanobacterial symbiosis

open access: yesNew Phytologist, EarlyView.
The heterocyst‐rich Encephalartos natalensis cyanobacterial zone in coralloid root suggests co‐option of conserved symbiosis‐associated genes. This figure was created in BioRender (BioRender.com/https://BioRender.com/n3qveqc). Summary Plant‐cyanobacterial symbioses have evolved independently at least four times across land plants, yet their underlying ...

The genetic architecture of leaf vein density and its importance for photosynthesis in maize

open access: yesNew Phytologist, EarlyView.
Vein types in maize leaves. Summary Leaf venation density has significantly increased during plant evolution. Higher densities are observed in angiosperms compared with early land plants, and among angiosperms, recently diverged C4 species have the highest values.

An 15N study of the effects of nitrate, ammonium, and nitrate + ammonium nutrition on nitrogen assimilation in Zea Mays L.

open access: yes, 1984
Bibliography: leaves 113-134.A brief review of the literature on the effects of nitrate and ammonium nitrogen sources on plant growth, and the assimilation of those nitrogen sources, has been presented.

Natural variation in OsMYB305 downregulating cytokinin‐mediated inhibition of leaf senescence contributes to regional adaptation in rice

open access: yesNew Phytologist, EarlyView.
Proposed regulatory model of OsMYB305 in leaf senescence. Summary Accumulating evidence has identified transcription factors (TFs) as key regulators of the onset and progression of leaf senescence. However, the regulatory role of the rice myeloblastosis (MYB) TF OsMYB305 in this process remains largely unknown.
